Lead and Crime

Byoliveridley

The next time Giuliani tries to take credit for the decrease in violence during his tenure as NYC’s mayor, send him this chart.

The NY Times shines some light on Jessica Reyes’ excellent work linking decreased lead exposure to a drop in violent crime in the US. The decreased lead exposure, of course, was from the phase-out of leaded gasoline from the American market. BTW, Nascar still uses leaded gasoline in its cars, nice going, guys.

The answer, according to Jessica Wolpaw Reyes, an economist at Amherst College, lies in the cleanup of a toxic chemical that affected nearly everyone in the United States for most of the last century. After moving out of an old townhouse in Boston when her first child was born in 2000, Reyes started looking into the effects of lead poisoning. She learned that even low levels of lead can cause brain damage that makes children less intelligent and, in some cases, more impulsive and aggressive (Emphasis Added).

Lead exposure at an early age (2-3 years) is especially significant as this is an age where personality development occurs and any interference in neuron development and apoptosis (death!) can cause permanent changes in personality. This excellent review article summarizes the effects of lead on neuronal development.

Reyes’ research mentions that while decreased lead exposure was very well correlated with violent crime (accounting for 56% of the reduction in crime), no correlation was found to property crimes (such as theft). This of course makes intuitive sense. A property crime is usually premeditated whereas violence is usually impulsive (excluding serial killers, of course). It is more likely that a budding criminal sets out to steal a car than to beat somebody to pulp. It is when the crime goes wrong that the probability of a violent crime increases. An individual with damaged impulse control is then more likely to seek a violent way out of the bad situation.

Our society (like most) views violent crime as a moral issue, a matter of good and evil that is determined by your “character”. So, a simple chemical correlator to violent crime that can explain a majority of the commission of violent acts goes a long way in undermining this whole notion of morality and crime. Of course, there are other sociological factors at play which need to be addressed. But it is heartening to know that beyond all the complicated and recalcitrant social issues that underly crime, there’s a ubiquitously evil pollutant lurking that can be eliminated. I am guessing that this line of reasoning is not going to be very popular among the “tough on crime” types that perpetrate our political airwaves these days.

  • The Onion on Conservation

    Byoliveridley

    This is so sad, though there is more than a kernel of truth to it. Individual efforts mostly make people feel better about themselves (hey, I recycle, makes me feel good!). It is the Onion and it does go too far. Of course individual efforts add up, and more importantly, force the important players like government and big industry to modify their behavior just a little bit (at least that is what I tell myself).

    I’m Doing My Inconsequential Part For The Environment | The Onion – America’s Finest News Source

    Every day, without fail, I meticulously organize my recyclables into five distinct categories, thereby subtracting an eyedropper’s worth of garbage from the countless tons of waste that ferment in our landfills. It only takes a few extra minutes, but just think of the impact it totally lacks. I also refuse to use anything but “Earth-friendly” paper products—some of which contain up to 10 percent recycled materials. For me, it’s worth shouldering the extra cost, but, unfortunately, only a scant few of us bother to do the same. And growing some of my own organic vegetables in my backyard garden also, to my immense gratification, reduces the use of toxic chemical-based pesticides and herbicides present in corporate farming techniques by as much as 0.0000000000000000000000000000000000000001 percent.

    The US guts Environmental Assessments

    Byoliveridley

    Environmental assessment in the U.S. was enshrined in law for the first time when President Richard Nixon signed the National Environmental Policy Act (NEPA) on January 1, 1970. Since then, however, the U.S. has slowly cast aside its role as a leader in the field of environmental assessments, as successive administrations have chipped away at the scope of NEPA, experts say. The cuts have reached a crescendo with President George W. Bush’s administration, and proponents of these assessments worry that pressure to develop natural resources with little oversight of the consequences will lead to an unsustainable future for the U.S.

    ES&T Online News: Environmental Magna Carta under siege

    Well, perfect. Now you can claim very factually that “you don’t know of any harmful effects of your actions”.

    The fact is, the attack on NEPA has come, chronically, from a relatively small group of commodity users—timber companies, highway builders—who simply oppose having the public and environmentalists get in the way of their plans and programs,” Houck maintains.

    Can’t say it any better. Information is very important and one thing this Bush administration has been very successful at is reducing the flow of information.

  • John Kerry and the Environment

    The fight in the Senate | Gristmill: The environmental news blog | Grist

    Kerry, everyone’s favorite democrat summarizes the non-coal/auto democrat’s energy/environmental policy plans int he US senate.

    Highlights:

    1. Increase Fuel Economy standards
    2. Increase contribution of renewable sources
    3. No drilling in the Alaskan National Wildlife Refuge (ANWR)
    4. No liquid coal
    5. NO MORE COAL WITHOUT SEQUESTRATION!!!

    This is all very sensible. He does not mention biofuels/corn ethanol, which I guess is because he’s from Mass, not exactly corn central.

    He’s a good man, this John Kerry.

    Organic agriculture can feed the world

    Byoliveridley

    That’s the conclusion reached by the authors of this study based on 293 examples in the developing and developed world.The authors also conclude that yields in the developing world are higher for organic agriculture than for conventional agriculture. Why? Well, since the paper is not open access, I can’t read it, or critique it, I’ll have to wait to get to the library before I can download it. But, maybe it’s because organic agriculture tends to be more labor intensive than conventional agriculture as practised by the developed world, and in the developing world, labor is cheap!

    Anyway, this is a good news study and should be examined a little more thoroughly.

    CJO – Abstract – Organic agriculture and the global food supply

    The principal objections to the proposition that organic agriculture can contribute significantly to the global food supply are low yields and insufficient quantities of organically acceptable fertilizers. We evaluated the universality of both claims. For the first claim, we compared yields of organic versus conventional or low-intensive food production for a global dataset of 293 examples and estimated the average yield ratio (organic:non-organic) of different food categories for the developed and the developing world. For most food categories, the average yield ratio was slightly 1.0 for studies in the developing world. With the average yield ratios, we modeled the global food supply that could be grown organically on the current agricultural land base. Model estimates indicate that organic methods could produce enough food on a global per capita basis to sustain the current human population, and potentially an even larger population, without increasing the agricultural land base. We also evaluated the amount of nitrogen potentially available from fixation by leguminous cover crops used as fertilizer. Data from temperate and tropical agroecosystems suggest that leguminous cover crops could fix enough nitrogen to replace the amount of synthetic fertilizer currently in use. These results indicate that organic agriculture has the potential to contribute quite substantially to the global food supply, while reducing the detrimental environmental impacts of conventional agriculture. Evaluation and review of this paper have raised important issues about crop rotations under organic versus conventional agriculture and the reliability of grey-literature sources. An ongoing dialogue on these subjects can be found in the Forum editorial of this issue.

  • Judges Overturn Bush Bid to Ease Pollution Rules – New York Times

    Judges Overturn Bush Bid to Ease Pollution Rules – New York Times

    But on Friday, the court said the agency went too far in 2003 when it issued a separate new rule that opponents said would exempt most equipment changes from environmental reviews — even changes that would result in higher emissions.

    With a wry footnote to Lewis Carroll’s “Through the Looking Glass,” the court said that “only in a Humpty-Dumpty world” could the law be read otherwise.

    “We decline such a world view,” said their unanimous decision, written by Judge Judith W. Rogers, an appointee of President Bill Clinton. Judges David Tatel, another Clinton appointee, and Janice Rogers Brown, a recent Bush appointee, joined her.

    The winners this time —more than a dozen states, including New York and California and a large group of environmental organizations — hailed the decision as one of their most important gains in years of litigation, regulation and legal challenges under the Clean Air Act.

    The provision of the law at issue, the “new source review” section, governs the permits required at more than 1,300 coal-fueled power plants around the country and 17,000 factories, refineries and chemical plants that spew millions of tons of pollution into the air each year.

    The proposed rule would have allowed powerplants to avoid putting new controls in as long as the cost of equipment did not exceed 20% of the replacement cost of the plant. Fuzzy math, anyone! This would have let to major incentives to not build new plants using cleaner technology, but keep the “grandfathers” running. A lot of the old plants were exempted from some of the strict controls by being grandfathered into the act. Well, call me cruel, but grandfathers eventually die! I thought of this proposed rule as the “Bionic Grandpa” provision! Glad that the courts did not like it.

  • How Safe Is The US Food Supply?

    Byoliveridley

    A good summary of the state of food safety regulation in the United States.

    How Safe Is The Food Supply?

    These known cases make up a tiny fraction of the overall problem–an estimated 76 million illnesses and 5,000 deaths in the U.S. from food poisoning each year. Meanwhile, imports of food, some from countries without strict controls, soared to more than 9 million shipments last year doubling since 2002. The cash-strapped FDA is able to inspect less than 1% of imports. It’s a recipe for disaster. “Our food-safety system in this country is broken,” warned former FDA Commissioner Dr. David A. Kessler at a recent congressional hearing.

    Few incidents ever have a body count high enough to shock the country into making fundamental changes. Overall, “we do have a very safe food supply,” says Sanford A. Miller, former director of the FDA’s Center for Food Safety & Applied Nutrition. But the alarms over pet food and vitamin A have lit a fire under lawmakers and executives. On May 2 the Senate rushed to pass a bill by a vote of 94-0 giving the FDA more responsibilities, such as creating databases of adulterated food. Meanwhile, food producers have been holding emergency meetings with suppliers, looking for problems in their factories or supply chains. Companies are “feverishly examining their own purchasing policies and trying to ensure they are followed,” says Kovacs.

    Note that it is always tempting to blame the bureaucrats here. Bureaucracy is a dirty word in this country, associated with “red tape”, “corruption”, “standing in the way of business”, “pencil pushers”, “big government”, you name it, they get called it. But, agencies like the EPA and the FDA have competent scientists who know what they are doing. But, without the money and the authority, which is given to them by the political arm of the government, they cannot do much. They have also, in recent years, been headed by political appointees who come from the industry they are supposed to regulate and show a distaste for regulation which is in complete opposition of the mandate they are supposed to fulfill as the head of a regulatory agency.

    It’s easy to take potshots at the FDA, but remember who gives them the money, makes the rules and tells them what not to oversee.
